Problems with the Z80 Assembler

Question

I am trying to write in the Z80 Assembler in the CP / M 2.2 emulator (z80pack) in Debian:

It just says “File not found” every time I try to write a line. I was looking for guidance, but he did not say how to start. Is there a special command I have to enter? Since the M80 (Macro-Assembler 80) also gives an error on every line.

Answer 1

You need to create a file containing your Z80 code called whatever.Z80, and then provide it whateverat the invitation %.

Therefore, you can edit your code to change your program, and not completely rewrite all the code every time.
